Soil structure
Topic

To understand the behavior of soil under stresses causing deformation or when fluids flow or diffuse through its pores, it is essential to introduce a model that describes its internal structure. We can approach this description by considering that soil is composed of a mixture of sand, silt, and clay particles, each with different shapes and sizes. The relative proportion of these components varies depending on the type of soil, and how these particles are arranged defines the level of porosity present in the soil.
